Current Research and Development Projects

• D-NAVIO Ship safety and reliability with intelligent digital twins.
  As maritime transport evolves, so do the risks. Complex, high-value vessels face mounting safety, environmental, and efficiency challenges, particularly as the sector moves towards automation. With this in mind, the EU-funded D-NAVIO project is developing a new kind of digital twin for ships: an Intelligent Digital Twin. Drawing on expertise from aviation, space, and automation, D-NAVIO combines explainable AI and self-healing tech to forecast and prevent failures. Tested on both a cruise ship and a container vessel, its tools include a digital twin library, a 'memory of failures' system, and advanced risk assessment models. By merging cutting-edge science with real-world insight, D-NAVIO aims to redefine safety, reliability, and sustainability at sea. D-NAVIO is funded by the European Commission Horizon program under Grant Agreement No. 101202933.
  Project duration: 48 months, started on June 01, 2025.

• MEDIATE Multi facEteD ImplementAtion of a mixed sofTwarE/hardware-based zero-trust framework for the computing continuum
  MEDIATE's vision is to produce a robust technology, which will address the security and privacy attributes of the computing continuum. For this, it will put forth a complex architecture that is based on the concept of zero-trust and will assume a federated learning approach in order to perform security-based scrutinisation at all continuum levels. i.e. IoT, edge and cloud, using security models that can be updated, redistributed and reconfigured across it. The actual features of the MEDIATE framework will support major topic outcomes such as cybersecurity resilience through reconfiguration, vulnerabilities mitigation through cyber threat analysis, secure integration at the IoT level through software and hardware-based security sensors and trust and security for massive ecosystems through the use of federated learning-based orchestration. Moreover, it will feature AI-based tools for cyber threat intelligence that assist a decision support system and privacy policies for data and identity protection. MEDIATE is funded by the European Commission Digital Europe program under Grant Agreement No. 101168465.
  Project duration: 48 months, started on November 01, 2024.

• CyberSecPro Collaborative, Multi-modal and Agile Professional Cybersecurity Training Program for A Skilled Workforce In the European Digital Single Market and Industries
  Fourteen (14) HEIs and thirteen (13) security companies from sixteen (16) EU countries propose the agile CyberSecPro professional cybersecurity practical and hands-on training program that will complement, support, and advance the existing academic programs by linking innovation, research, industry, academia and SME support. CyberSecPro aims to bridge the gap between degrees, working-life and marketable cybersecurity skill sets necessary in the digitalization efforts and become the best practice for all cybersecurity training programs. CyberSecPro is funded by the European Commission Digital Europe program under Grant Agreement No. 101083594.
  Project duration: 48 months, started on December 01, 2022.

• Controlling Current Change (CCC) Security and Integrity Project: The Research Unit ``Controlling Concurrent Change (CCC)'' examines the challenges the independent software updates will face due to an increasingly openly interconnected future, and how these challenges can be met. The Research Unit will therefore look for ways of how to control the variety of updates of different software applications without side effects, and how to make computer platforms more robust to ensure proper functioning of different software subsystems.
  Within the overall framework of CCC, the Security and Integrity Project looks at flexible security policy enforcement mechanisms that can ensure that misbehaving components cannot interfere adversely with the overall system of the execution of other components.
  CCC is funded by the Deutsche Forschungsgemeinschaft (German Research Foundation) for 3 years with the prospect of a second 3 year funding period begun on April 1, 2013.

• Secure Hardware-Software Architectures for Robust Computing Systems (SHARCS): This project is funded under the EU H2020-ICT-2014-1 call. SHARCS is a framework for designing, building and demonstrating secure-by-design applications and services, that achieve end-to-end security for their users. SHARCS will achieve this by systematically analyzing and extending, as necessary, the hardware and software layers in a computing system.
